How do I tell my family about the layoff? - what worked for you?

My spouse does not know yet that I was let go as an event coordinator. I have read a lot of threads here and could not find my exact situation. I want a plan before I speak. What did you say?

Kids often pick up more than you think. A short, calm explanation helped mine feel secure.

Do not wait until a bill surprises them. The longer it goes, the harder it gets.
